A general approach to posterior contraction in nonparametric inverse problems
Bartek Knapik, Jean-Bernard Salomond
In this paper we propose a general method to derive an upper bound for the contraction rate of the posterior distribution for nonparametric inverse problems. We present a general t…

Semiparametric posterior limits under local asymptotic exponentiality
Bas Kleijn, Bartek Knapik
Consider semiparametric models that display local asymptotic exponentiality (Ibragimov and Has'minskii (1981)), an asymptotic property of the likelihood associated with discontinui…
